SPECIFICATION forming part of Letters Patent No. 646,427, da d April 3, 1900.

- Application filed February 24, 1899. Serial No. 706,576. 7 (No model.)

To all whom itmcby concern:

Be it known that I, JEAN FRANOOISGUAY, a subject of Her Majesty the Queen of Great Britain, residing at Plessisville, county of Megantic, Province of Quebec, Canada, have and successively opened to drop a predeter mined charge intothe generating-chamber.

A further object is to provide a construction which is neat and attractive in appearance, durable in construction, simple and efficient in operation, and which can be made at a low cost.

To these and other ends myinvention consists in the improved construction and combination of parts hereinafter fully described, and particularlypointed out in the appended claims.

In the accompanying drawings, forming a part of this specification, and'in which similar numerals of reference indicate similar parts in both views, Figure 1 is a front elevation, partly in section, of myimproved gen erating apparatus. Fig. 2 is a detail of the mechanism for successively opening the carbid receptacles or chambers.

1 designates the gasometer, formed of the section 2 and telescoping section 3, said section 3 being mounted to have a vertical movement'within the frame 4:, as shown in Fig.1.

5 designates the generator, having a removable cover 6, sealed to prevent the escape of gas therefrom. The generator is connected to the gasometer by means of a suitable pipe '7, mounted centrally within said generator and extending outwardly through the side thereof and into a pipe 8, which leads into the gasometer, the pipes 7 and 8 forming the gas-conduit from the generator to the-gas ometer.

Secured within the periphery ofthe generatornear its top are a series of pockets or can drop from said compartment; but when the catch 11 is tripped the door will fall,,thus allowing the carbid to drop into the water contained in the generator, thus generating gas, which passes upward and out through the pipe 7 and pipe8 into the gasometer.

As the pockets or chambers 9 arearranged in series and as it is necessary only that but one chamber or pocket be emptied at a time, it is necessary that the mechanism be so constructed as to cause but one catch to be operated at a time, and this is accomplished by means of a suitable collar 12,slidably mounted onthe pipe 7. Theface of the collar is provided with a series of laterally-extending portions 13, arranged at dilferent heights, as best shown in Fig. 2. The collar 12 is moved vertically by means of .a suitable rocking lever 14, formed substantially as shown in Fig. 2, said rocking lever having a pitman connection with the collar, as shown in said figure.

As shown in the drawings, therocking lever extends to a point within the generator, having one of its arms extending inwardly to approximately the center of, the generator and having its arm on the outside of the generator extending rearwardly and having at its end a bar or upright 15, pivotally connected thereto, said bar having at its upper end a lateral extension 16, at the end of which is pivotally mounted an L-shaped rocking arm 17, the parts being substantially as shown in Fig. 2.

While I have described but one generator and its mechanism, it is to be understood that I I mayuse a plurality of generators and mechanism for operating, and in the drawings I have so shown the apparatus, each generator being a duplicate of the other.

In operating my improved apparatus the one compartment.

receptacles for the carbid (designated as 9) are filled, the doors 10 being in their locked position. position shown in full lines in Fig. 2, the otherarm, located on the opposite side of the gasometer, being placed in the position shown in dotted lines in this figure. As the section 3 of the gasometer passes downward, a plate 18, extending laterallyfrom the top of said section, contacts with the upper end of the arm 17, whereupon by the continued downward movement of the section 3 the rocking lever 14. will be oscillated, raising the collar 12 upwardly on the pipe 7until the uppermost portion 13 formed on said collar con tacts with and opens its catch 11, thus releasing the,door from the compartment to which the catch is attached. The dropping of the carbid necessarily forms the gas, causing the section 3 to be raised, and as this section rises the weight of the collar 12 causes it to descend to its normal position. This action is repeated each time the section 3 is lowered, each lowering of the section causing the collar 12 to be moved to a greater height as the successive portions 13 are successively brought into contact with the catch 11 which is operated by said portion. During this movement of the section 3 the opposite plate 18 passes downward in a manner similar to the one which isoperating the active generator; but inasmuchas the arm 17 is out of the path of movement of said plate there will be no action of the rocking arm of the inactive generator until the carbid in the active generator has been removed, with the exception of During the downward movement of the section 3 to cause this last compartment to be opened the opposite plate reaches a position where it contacts with the lowerarm of the arm 17, causing the entire arm 17 to be rocked and to be brought into position asshown, the upright portion of the arm 17 remaining outside of the path ofmovement of the plate 18 until such plate has moved above the top of said arm, when the weight of thelower arm will-cause the arm 17 to assume this position. (Shown in full lines in Fig. 2.) Upon the next downward movement of the section 3 the second generator will come into active operation, while the generator before used will be free from any making of gas, owing to the absence of the carbid, the collar 12 in the inactive generator having a movement corresponding to the movement of the collar within the active generator; but such movement does no harm, inasmuch as all of the compartments have been'emptied of their contents.

As shown in Fig. 1, each of the pipes 7 is provided with a suitable cook 19, whichserves to allow of the closing of the pipe 7 from operative connection with the interior of the gasometer. It will also be seen that each of said pipes is connected to the pipe 8, which leads directly within the generator, forming the conduit for the gas from each generator.

One of the arms 17 is placed in the It will also be seen that the pipe 8 is continued upwardly from the connection with the pipe 7,- the upper end being provided with a suit able annular receptacle 20, adapted to receive water to form a water seal, with'a suitable cap 21, formed substantially as shown in said figure. The cap 21 is formed with an interior opening, to which is operatively connected an opening 22, formed within the curved pipe 23, secured to the cap 21. The cap 21 is adapted to be placed over the upper end of the pipe 8, a suitable ring 24 serving to retain it in its position on said pipe, while the extension-pipe 23 is adapted to pass withina suitable outlet-pipe 25, forming the safety-pipe for the carrying of the excess of gas. By this construction it will be seen that as the gas is formed it passes into the gasometer until the section 3 has reached a proper position. When this position has been reached, should the pressure within the section 3 become greater, and as the safety attachment just described is regulated to withstand but a predetermined amount of pressure or when the pressure within the section 3 becomes more than is normally required, the cap 21 will be forced upwardly, carrying with it the extension 22, which passes within the pipe 25, until the opening 22 passes above the water-level of the annular receptacle 20, whereupon the gas will escape through the opening 22 into the pipe 25, and thus to the outeratmosphere. When the pressure is reduced, the cap 21 will pass downward to its normal position,such

passing downward causing the'opening to be automaticallyclosed, and thus prevent the escape of gas.

Each generator is provided with a suitable opening 26, closed by means of a plug 27, by

means of which the residue collecting at the bottom of the generator can be readily re moved. The gasometerisconnected to the service-pipe .by means of a suitable pipe 28, leading into the interior of the gasometer, as shown in dotted lines in Fig. 1.

The advantages of this construction are many, including theease andsimplicity with which the apparatus can be operated, the automaticdropping of the carbid, and the eflicient safety apparatus, bymeans of whichall excessive gas may be readily removed.

If desired, the cap 21 may be provided with an upwardly-extending rod 26, (shown in dotted lines in Fig. 1,) said rod having its upper end provided with a cross-piece, as shown. To cooperate with this rod, I place a suitable loop 27 on the bell of the gasometer, said loop encircling the rod. By-such construction it will be seen that when the bell of the gasometer reaches the position where it is desired to prevent a further upward movement the loop 27 abutsagainst the cross-rod and by the upward movement of the bell causes the cap to be raised, thus opening communication between the gasometer, generators, and escape-pipe.

While I have herein shown a preferred in so far as such modifications and changes.

form of carrying my invention into effect, yet I do not desire to limit myself to such preferred details of construction, but claim the right to use any and all modifications thereof which will serve to carry into effect the objects to be attained by this invention may fall within the spirit and scope of my said invention.

Having thus described my invention,what I claim as new is 1. The combination with a gasometer; of a generator; a series of carbid-receptacles secured within said generator, each receptacle having a hinged door; means for holding said doors in their closed position; and a collar, mounted to have a vertical movement within said generator, said collar having a series of lateral projections, located at different heights, said projections being adapted to contact with said door-closing means, successively, whereby the receptacles will be emptied independently and successively.

2. The'combination with a gasometer; of a generator; a series of carbid-receptacles secured Within said generator, each receptacle having a hinged door; means for holding said doors in their closed position; a collar mounted to have vertical movement within said generator, said collar having means for successively tripping said door-closing means; and a rocking lever operatively connected to said collar, and operated by the movement of said gasometer, for successively bringing said tripping means into operation with said door-closing means, whereby the receptacles will be emptied independently and successively.

3. An acetylene-gas-generatingapparatus, comprising a gasometer; a generator; a series of carbid-receptacles secured within said generator, said receptacles being arranged about the inner periphery of said generator; a door hingedly connected to said receptacles,

each receptacle having an independent door,

said doors being adapted to normally close said receptacles, each door extending radially toward the center of said generator; a catch for each doo'r, adapted to normally hold the door closed, said catch extending in- Wardly toward the center of said generator; and means, operated by the movement of the gasometer, and movable vertically within said generator, for successively tripping said catches, whereby said doors will be released and said receptacles emptied independently and successively.

4. The combination with a telescoping gas ometer; of a plurality of generators operatively connected thereto, each of said generators having a series of carbid-receptacles; doors hingedly connected to said receptacles, each receptacle having an independent door,

said doors being normally in a closed position; a tripping mechanism mounted within each generator; a rocking lever adapted to be operatively connected to said tripping mechanism, the movement of said lever being adapted to impart a vertical movement to said tripping mechanism, whereby said doors will be released; and means, automatically operated by the movement of the bell,

of the gasometer, for imparting movement to said rocking levers, said means being auto matically brought into operative position by the movement of said bell.

In witness whereof Ihave hereunto set my hand in the presence of tWo witnesses.
